摘要： A method and apparatus for measuring activity in the peripheral nervous system comprises a nerve cuff having an array of chemical detectors such as chemFETS or ISFETS. Activity within the nerve causes chemical responses which can be detected. The use of chemical rather than electrical detection minimises interference problems and allows the cuffs to be made smaller.

摘要： A current feedback operational amplifier input stage is provided that uses a pair of dual output current mirrors to couple current from the inverting input of the amplifier to the high gain node of the amplifier, and to reduce the input impedance of the inverting input by means of local current feedback. Each of the dual output current mirrors employs an emitter degenerated Wilson-type current mirror in conjunction with an emitter degenerated transistor current source to detect signal current at the inverting input and use this current to control the bias current at both the inverting input and the high impedance node of the amplifier. The ratio of bias currents in the dual output current mirrors are controlled by scaling the resistances of the emitter degeneration resistors corresponding to each current node.
